Why would you want to do this? Can you just change your software to use abcd.com instead of 23.45.66.77, that way it's easy to remap the IP?

I think your answer would be you would need a transparent proxy. But how to do that in windows is a problem! this guy got squid(a web proxy) with something like a transparent proxy of some kind. markus.revti.com/2009/01/…

Routing won't solve the problem. The destination IP address in the packets will still be 23.45.66.77, not 127.0.3.3 so the interface won't actually be able to receive the packet.
